"The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 billion years ago. These fossils are of structures known as stromatolites, which are, in many cases, formed by the growth of layer upon layer of single-celled microbes, such as cyanobacteria. (Stromatolites are also made by present-day microbes, not just prehistoric ones.)
The earliest fossils of microbes themselves, rather than just their by-products, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago
Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago. However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible)."

Answer:
The answer is "Option e".
Explanation:
please find the complete question in the attached file.
Its long tail disregards its short tail. Let's assume that even a short neck is a as well as a tail over, which claim, though, the short tails were mixed, shorter, and longer tailed mousses are created. It may also presume that the short mouse parental is always Aa. And we get AA, Aa, Aa, Aa, and Aa situations once their matter and they fall pregnant to both high and short tail mice but we wouldn't get the fat tail mouse unless the tail-mouse were as AA.
we always get two types of lines. It demonstrates there was no uniform AA genera. It is a case of the heterozygous dangerous gene, that can cause a set of identical alleles inside an organism to always be lethal.
The independent variable is the water temperature because it is not dependent on the change of another variable so the answer would be D
